Patented Nov. 12, 1946 UNITED STATES. PATENT OFFICE 2 Claims. 1.

This invention relates to cloth guides for sewing machines, and it hasfor its object to provide a cloth guide which is simple in constructionand inexpensive to manufacture, which can be readily adjusted withoutthe use of a screw driver or other tools, and alsobe'readily moved froman operative to a raised inoperative position with out the use of suchtools.

In order to give anunderstanding of'my invention, Ihave' illustrated i'nthe drawing a selected embodiment thereof which will'now be described,after which the novel f'eature'swill be pointed out in the appendedclaims.

In-the drawing- Fig. l isa fragmentary, perspective view of'a part-of asewing machine illustrating my improvements. Fig. 2 is a side View ofFig. 1; Figs. 3 and 4 are enlarged sections on the line 3-3 Fig. L'Fig;3 showing the position of the parts when the cloth guide is in itsoperative position, and Fig. 4 showing the position of the parts whenthe cloth guide is in its raised, or inoperative position. Fig. 5 is aview of the cloth guide looking from the rear. Fig. 6 is a section onthe line 6-6 Fig. 5.

In the drawing I indicates a part of the head of a sewing machine, 2represents the presser bar having the presser foot 3 at its lower end,and 4 represents the needle bar carrying the usual needle 5.

My improved cloth guide is constructed to be attached to, or mounted onthe presser bar 2. The cloth guide comprises a supporting block 6 whichis mounted on the presser foot bar 2 and is held in adjusted positionthereon by a set screw I.

The cloth guide element is indicated generally at 8' and it comprises astem portion 9 which extends through an aperture formed in thesupporting block 6, and an arm portion In extending laterally from oneend of the stem portion 9 and terminating in its free end in aclothguiding portion II which forms a guide for the edge 25 of thecloth, or work piece 26, that is being stitched as shown in Fig. 1,wherein 21 i represents the line of stitching being made in the cloth26.

The stem 9 can be adjusted in the block 6 so as to bring the cloth guideportion II nearer to, or further from, the line of stitching, and saidstem can also be turned in the block so as to permit the cloth-guidingportion II to be swung upwardly in to a raised, inoperative positionsuch as shown in dotted lines in Fig. 2, or to be lowered into itsoperative position shown in full lines in Figs. 1 and 2.

My improvements also include a novel means for holding the cloth guidein any adjusted position. Such means is in the form of a locking leverI2 which is pivotally mounted on th -block 6 and which has atone end adepending locking flange I3 which is adapted to engage in any one of aseries of notches I I with which the stem portion 9 is provided. Thelocking lever I2 is shown as having a flange I5 depending from its backedge, whichflange overlies the rear end of the block 6 and ispivotally'connected thereto'by means of a pivot screw I6. N indicates aspring interposed between the block and the lever l2, which spring actsto yieldingly'hold the flange, or nose, I3 against the stem; The.locking. lever I2 is formed at its free. end with a thumbpiece I8, the.construction. being: such: that when. pres. sure is applied-to thethumbpiece I8; the leven will be turned about its pivot therebydisengaging the nose I3 from one of the notches in the stem 3. When thenose has been thus disengaged, the stem can be adjusted in the block 6so as to place the cloth-guiding portion I I nearer to, or further from,the needle 5.

Each notch I4 is so formed that it co-operates with the nose I3 not onlyto hold the cloth-guiding element in any adjusted positionnearer to, orfurther from the needle, but also to hold the cloth-guiding arm in itsraised position shown in dotted lines Fig. 2.

For this purpose each notch is so cut that it presents a fiat bottomportion I9 of considerable length which merges into the curved endportion 26. Each notch is so positioned circumferentially of the stem 9that when the cloth guide is in its operative position shown in Fig. l,the end portion of the notch I4 having the curve bottom 28 will be onthe upper side of the stem and will be the portion of the notch whichreceives the nose I3. This is the position of the notch indicated inFig. 3. 1

When the clothguiding member is raised or swung upwardly into itsinoperative position shown in dotted lines in Fig. 2, the resultantturning motion of the stem 9 about its axis will bring the notch I4 intosuch position that the flat bottom portion I 9 thereof registers withthe straight edge 2| of the nose I3 as. seen in Fig. 4. The action ofthe spring I! holds the straight edge of the nose I3 in engagement withthe fiat bottom IQ of the notch with sufficient pressure to retain the Wcloth guide in its raised inoperative position.

can be performed without the necessity of using a screw driver or anyother tool.

The adjustment of the cloth guide toward and from the needle can also beaccomplished without the use of any tools, all that is necessary beingfor the operator to press downwardly on the finger piece l8 so as todisengage the nose I3 from the notch and then to slide the stem 9 in theblock 6 thereby to bring the cloth-guiding portion l I into its desiredposition.

If desired, I may make the finger piece I8 so that one edge 22 thereofwill present a sharp cutting edge. This cutting edge can be used forcutting the thread.

I claim:

1. A cloth guide for sewing machine comprising a supporting blockadapted to be mounted on ing portion, a locking arm pivoted to the blockand having a nose portion adapted to engage in any one of the notchesand thereby hold the cloth guiding member in adjusted position, and aspring acting on the locking arm and yieldingly holding the nose portionthereof in operative position, said nose portion having a straight edgeand each notch being formed so that its bottom presents a straightportion and a shorter curved portion, said straight and curved portionsbeing so disposed that when the cloth guiding member is in its operativeposition, the nose of the locking arm rests on the curved portion of thenotch bottom, while when the stem is turned to place the cloth guidingmember in its raised inoperative position, the straight edge of the noseportion rests on the straight portion of the notch bottom and therebyholds the cloth guiding member in such raised position.

2. A cloth guide for sewing machines comprising a supporting blockadapted to be mounted on the presser foot bar of a sewing machine, acloth guiding member having a stem portion extending transverselythrough said block and alsohaving an arm portion extending laterallyfrom one end of the stem portion and terminating in a cloth-guidingportion, said stem portion being adjustable in the direction of itslength in said block for shifting the position of said clothguidingportion and also being turnable in said block to-swing the cloth-guidingportion from an operative position to a raised inoperative position,said stem portion being provided with aplurality of notches, the bottomof each notch presenting a straight section extending from one endthereof well towardthe other end, which straight section merges into a'section of thenotch that extends to the other end thereof and has acurved bottom, a locking arm pivoted to the block and having a dependingnose'portion adapted to engage in any one of the notches and having astraight edge, and a spring acting on the locking arm and yieldinglyholding the nose portion thereof in engagement with any slot, theengagement of said nose portion with any slot holding, the cloth guidein adjusted cloth-guide position, and when the cloth guide is turned toplace the clothrguiding portion in elevated position the engage-' mentof the flat edge of the nose with the fiat section of the notch bottomserving .to hold the cloth guide in its raised position.
